CHICAGO (AP) — A 55-year-old patriarch of a violent street-gang faction in Chicago was arrested Thursday along with 34 other Gangster Disciples on charges related to the running of a lucrative heroin- and crack-cocaine operation, according to prosecutors.

Johnny “Goo” Herndon presided over open drug markets on the city’s west side that generated more than $160,000 in revenue a month in crack sales alone, a 178-page federal complaint alleges.
